4-HO-DPT Powder

Starting from €37.50


4-HO-DPT is officially known as 4-hydroxy dipropyltryptamine, and occasionally referred to as Procin. 4-HO-DPT is a psychedelic substance of the tryptamine class. 4-HO-DPT is first synthesized by Alexander Shulgin and documented in his book TiHKAL (Tryptamines I Have Known and Loved). Researchers use it as an entheogenic compound. Very little research data exists about the properties of 4-HO-DPT; therefore, 4-HO-DPT is a fascinating chemical with many research potentials. In comparison to other tryptamines such as 4-HO-DMT and 4-AcO-DMT, 4-hydroxy dipropyltryptamine is extremely similar in possible outcomes.

A psychedelic substance of the tryptamine class and related to it’s backbone DPT, also known as Dipropyltryptamine "The Light".   Chemistry background information 4-HO-DPT As with most psychedelic tryptamines, 4-HO-DPT is believed to act primarily as a 5-HT2A partial agonist. The psychedelic properties are believed to result from the results of 4-HO-DPT on the 5-HT2A receptors. However, the role and outcomes of these interactions remain elusive and will require further scientific investigation. Substances of the Tryptamines class share a core structure consisting of a bicyclic indole heterocycle linked at R3 to an amino group. 4-HO-DPT is substituted on R4 of its indole heterocycle with a hydroxyl functional group OH−. It also contains two propyl chains bonded to the terminal amine RN of its tryptamine backbone (DPT).   Where to buy 4-HO-DPT 4-HO-DPT can be purchased here on the Realchems website.
